RAlLROAD=TlE SPECIFICATION forming part of Letters Patent. No. 391,704, dated October 23, 1888.

Application filed February 16, 1888. Serial No. 264,172. (No model.)

To all whom it may concern.-

Be it known that I, LEVI HAAS, a citizen of the United States of America, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Railroadlies, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in metallic railroad-ties, having for its object the production of a tie composed, preferably, of integral parts for locking and securing a rail in position and holding the same as against displacement by reason of contraction or expansion of the metal.

The invention consists in the peculiar construction and arrangement of parts, substantially as shown and described.

In the accompanying drawings, Figure 1 is a View in perspective of my improved tie. Fig. 2 is a plan view. Fig. 3 is acentral lon gitudinal sectional view. Fig. 4 is an end view, and Fig. 5 is adetail perspective view, of one of the locking-arms with parts broken away.

Referring to the drawings, A designates my improved metallic tie, in the center of which is formed a groove or opening, a, by turning down flanges a, which hold the tie embedded in the earth. I have also shown a lip, a pro jecting from the bottom of the tie, which is to be used for attaching the tie to beams of a trestle or bridge, suitable bolts being passed through apertures of said lip. From the ver' tical longitudinal sides of the tie A project upward extensions B B, from which are formed bent locking plates or arms I) 0, having extended ends b, as shown. In the center of the outer portions or thickness of these extensions B are formed rectangular grooves or openings 1), and from the lower portions of these open ings project short horizontal extensions 1) b whereon the rail is designed to rest. In each locking plate or arm I), which forms the inner thickness of each extension B, is formed a groove or recess, if, of a shape corresponding to the flange of the rail.

After the rail is secured in position the locking plates or arms I) are forced against the inner surfaces of the outer thickness of the extensions B and lock the rail firmly in position, the extended ends I) of said plates or arms titting snugly under the horizontal extensions Z)". By this means the rail is firmly locked in position and is so tightly held that contraction or expansion of the parts will not ordinarily loosen the hold of the looking-plates, but should the same become loose a few taps with a hammer on the locking-plates will again tighten the parts.

To provide additional support for the rail, I insert a block, G, between the sides of the tie,

and hold the same by spikes, the heads of which overhang the flange of the rail.

One of the many advantages of my invention is the dispensing with spikes for securing the rails in position, and by means of my invention the rails will be firmly held against any liability of being deranged by contraction or expansion of the parts, and the same embodies many advantages in point ofsimplicity, durability, and general efficiency.

I claim as my invention 1. Ametallicrailroad-tie having upwardlyprojectiug extensions, and locking plates or arms formed therewith for securing a rail, substantially as shown and described.

2. A metallic railroad-tie having recesses formed in its sides, horizontal extensions projecting therefrom, and locking plates or arms, substantially as shown and described.

3. A metallic railroad-tie having recesses formed imits sides, and locking plates or arms provided with extended ends for locking the rail in position, substantially as shown and described.

In testimony whereof Iaffix my signature in presence of two witnesses.
